Answer:
She needs 112 ounces of Solution A and 48 ounces of Solution B.
Step-by-step explanation:
If a is the ounces of Solution A, and b is the ounces of Solution B, then:
a + b = 160
0.45a + 0.95b = 0.60(160)
Solve the system of equations. Using substitution:
0.45a + 0.95(160 − a) = 0.60(160)
0.45a + 152 − 0.95a = 96
56 = 0.5a
a = 112
b = 48
She needs 112 ounces of Solution A and 48 ounces of Solution B.
